I think the powered bass is great. I owned the Odyseys's for two years ran them with world class equipment. In a dedicated media room with properly treated accoustics. So I feel I got the most, I could out of them. They are a very musical speaker. However, they
are not close to the Summits in any regard. Summits are better from top to bottom. With the Odysseys I always felt I was had to chose ultimate bass, which ment using a soild state amp. Or great panel peformance using a tube amp. Now with the Summits using my Mcintosh MC 2000 amp, I have not heard better recorded music. And I heard a $150,000 system this week. Which did great "hi-fi" but did not make music. Just my 2 cents. NOTE The break in time is real and long. I hated the Summits for the first 3 months, only kept them because I trusted the company. I am glad I did.
I personally think the Summits are SO World Class, with vocals, accoustic music, jazz, small scale classical, they are just o.k. with amplified music, that if one hears them and does not love them, they are hearing the flaws of equipment and cables up stream. I know all the Wilsons you mentioned very well, they are not in the same leauge other then with rock music, which they are better at.
Just my 2 cents.
